This how you set the equation up.
2x + 6 = 3x + 7 
Subtract 6 from both sides.
2x = 3x + 1
Subtract 3x from both sides.
-1x = 1
Divide.
x = -1.
Now solve for y by plugging in the variable.
y = 2(-1) + 6
y = -2 + 6
y = 4
So your solution is (-1,4).
I hope this helps love! :)

Find the length of the third side. If necessary, write in simplest radical form.
Angelina_Jolie [31]

Answer:

the length of the missing side is 2

Step-by-step explanation:

Use a^2 + b^2 = c^2

a = 4

b = ?

c = 2sqrt5

4^2 + b^2 = (2sqrt5)^2

16 + b^2 = 20

subtract 16 from both sides

b^2 = 4

take the sqrt of both sides

b = 2

Sav [38]

<u>Answer:</u>

The correct answer option is 'Every tenth student in the main hallway between class.'

<u>Step-by-step explanation:</u>

Every tenth student in the main hallway between class would best represent the sample population since majority of the students transit this hallway unlike the rest of the options.

For instance, polling every tenth student in the library at lunch would result in the favor of views of students who frequently visit the library and polling every tenth student in the student section at the school football game would go in favor of those who prefer sports.
